ABSTRACT

FIXTURE FOR DETACHABLY MOUNTING TOILET SEAT ON TOILET BOWL WITHOUT THE USE OF TOOLS, FIRMLY HOLDING THE SEAT IN POSITION AND ENABLING REMOVAL OF THE SEAT BY LIFTING THE SEAT AND THE HINGE PIN FOR THE SEAT AND POST PARTS OF THE FIXTURE. THE FIXTURE INCLUDES TWO SOCKET MEMBERS EXTENDING THROUGH THE BACK PART OF THE TOILET BOWL AND SECURED THERETO AS NUTS, AND POSTS FOR THE HINGE PINS, EACH POST HAVING A LOCKING PIN DEPENDING THEREFRON WITHIN THE SOCKET OF THE SOCKET MEMBER AND CAMMING THE SOCKET MEMBER TO BE LOCKED THERETO BY PRESSING EACH POST AND PIN DOWNWARDLY ALONG ITS SOCKET. A DETENT LOCKING CONNECTION IS PROVIDED BETWEEN THE SOCKET AND PIN. THE POSTS, PIN AND   SOCKETS ARE MADE FROM A SUITABLE THERMOPLASTIC MATERIAL HAVING GOOD MEMORY QUALITIES, TO ASSURE A SNAP GRIPPING ACTION OF THE DETENT LOCKING CONNECTION AS THE PINS ARE INSERTED INTO AND WITHDRAWN FROM THE SOCKETS.

Int. Cl. A47k 13/12 US. Cl. 4-240 2 Claims ABSTRACT OF THE DISCLOSUREFixture for detachably mounting toilet seat on toilet bowl without theuse of tools, firmly holding the seat in position and enabling removalof the seat by lifting the seat and the hinge pin for the seat and postparts of the fixture. The fixture includes two socket members extendingthrough the back part of the toilet bowl and secured thereto as by nuts,and posts for the hinge pins, each post having a locking pin dependingtherefrom within the socket of the socket member and camming the socketmember to be locked thereto by pressing each post and pin downwardlyalong its socket. A detent locking connection is provided between thesocket and pin. The posts, pins and sockets are made from a suitablethermoplastic material having good memory qualities, to assure a snapgripping action of the detent locking connection as the pins are in-Serted into and withdrawn from the sockets.

BACKGROUND OF INVENTION This application is a continuation-in-part of myapplication Ser. No. 659,488, filed Aug. 9, 1967, now abandoned.

SUMMARY OF THE INVENTION AND OBI ECTS Simple snap action locking pin andsocket connection for the hinge pin for a toilet seat, retaining seat toa toilet bowl for ready removal and replacement, and held in position bya snap action detent connection maintained by the material from whichthe locking pin and socket are made.

A principal object of the present invention is to provide a simple snapaction pin and socket connection for detachably retaining a toilet seatto a toilet bowl and accommodating ready removal of the seat forcleaning.

Another object of the invention is to provide a removable toilet seatand cover for toilet bowls, including fixtures forming mountings for thepivots for the toilet seat, made from a thermoplastic material havingmemory qualities, retained in firm position on the bowl by a snap actiondetent connection, and readily removable by pulling upwardly on thetoilet seat.

Another object of the invention is to provide a fixture for the hingepin for a toilet seat made from a plastic material and retained to thetoilet bowl without the use of the washers heretofore required, andremovable by a simple upward pulling action on the toilet seat, withoutthe use of the usual tools.

Still another object of the invention is to provide an economicalmounting for the hinge pin for a toilet seat enabling replacement andremoval of the seat by a straight downward or upward pulling action onthe seat, in which the seat is firmly held to the bowl by a snap actionconnection.

Other objects, features and advantages of the invention will be readilyapparent from the following description of a preferred embodimentthereof, taken in conjunction with the accompanying drawings althoughvariations and modifications may be effected without departing from thespirit and scope of the novel concepts of the disclosure.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a top plan view of a toilet bowlhaving a toilet seat and lid hingedly retained to the bowl by a seatretaining fixture constructed in accordance with the principles of thepresent invention.

FIG. 2 is an exploded view of a fixture for one end of a hinge pin forthe toilet seat constructed in accordance with the principles of thepresent invention, with the socket member in section and shown asextending through the mounting flange for the toilet seat; and

FIG. 3 is a sectional view taken through one of the hinge pin fixtures,substantially along line III-III of FIG. 1.

DESCRIPTION OF PREFERRED EMBODIMENT OF INVENTION In the embodiment ofthe invention illustrated in the drawings, I have generally shown inFIG. 1 a toilet bowl 10 having a reduced area rear seat mountingposition 11 extending to the conventional tank 12. I have also shown atoilet seat and cover indicated generally by reference character 13 of aconventional form and including a seat 15 having a reduced width backportion having spaced ears 16, 16 extending rearwardly therefrom andforming a means for attaching the seat to the toilet bowl by a hinge pin17. Said hinge pin extends through said ears and beyond opposite sidesthereof and also may form a mounting for a reduced width rear portion 19extending rearwardly of a lid 21 for the toilet seat. The toilet seat15, lid 21 and reduced width rear portion 19, and hinge pin 17 may be ofvarious conventional forms so need not herein be shown or describedfurther. The seat may or may not have a lid, depending upon the locationof the toilet bowl.

Referring now in particular to the detachable mounting for opposite endsof the hinge pin 17, hinging the seat and cover to the toilet bowl 10,an individual upright toilet seat hinge mounting post 22 is provided toform a mounting for each end of the hinge pin 17. The post 22 has aretainer pin 23 depending therefrom and adapted to be carried in asocket 25 having a cylindrically shaped sidewall of a socket member 35,extending through the reduced width mounting portion 11 of the toiletbowl and secured thereto as by a nut 26.

The post 22 is shown in FIGS. 2 and 3 as having fiat top and bottomwalls 27 and as having a generally cylindrical wall portion 28 extendingbetween said walls. The cylindrical wall portion 28 is cut away for aportion of its length to provide an inwardly facing plane vertical face29, terminating at its lower end into a downwardly sloping beveled face30 extending to the cylindrical wall of said post a short distance abovethe bottom wall 27. The retainer pin 23 is shown as being formedintegrally with the post 22 and extending downwardly from the bottomwall 27 thereof in axially aligned relation with respect to the axialcenter of the cylindrical wall portion 28 of said post 22. The flatinwardly facing plane face 29 is shown as having a drilled hole 31leading thereinto and forming a mounting for an end of the hinge pin 17.The flat inwardly facing plane face 29 is also adapted to be abutted bythe outer side of an ear 16 for the toilet seat. The post 22 andintegral retainer pin 23 depending therefrom are preferably made from aplastic material having long memory retaining qualities, with someinherent lubricating qualities, accommodating ready insertion of theretainer pin 23 in the socket 25 for removal and replacement in saidsocket over long periods of years. A suitable plastic material is apolyethylene material, although a nylon plastic material is also asuitable material as are various other well-known forms of plastics.

The retainer pin 23 has a V-shaped annular groove or Oct. 19, 1971 F. A.SANSONE REMOVABLE TOILET SEAT Filed May 21, 1969 1 5 w 7 0 R Z v 5 0 f05 3 W N 3 J A A V 1 F A. 3 I n m K k L 2 a F 5 in. 9% fl J a] 20/ a 5 5Z M (Iii I fi/A/l 1 1! W -l i I 2/ a /7 3 9 h 7. Z 5 Z X J 7. Z

wherein the detent and groove means includes a V- shaped grooveextending about each retainer pin adjacent the lower end portion thereofand each retainer pin has a conical leading end portion extendingbeneath said groove,

wherein the socket member has an internal cylindrical side Wall having agenerally V-shaped detent projection extending inwardly of saidcylindrical side wall and intersected by said at least one radial slot,

whereby the conical leading end portions of said retainer pins engagesaid detent projections upon insertion of said retainer pins within saidsocket members and cam said detent projections outwardly to make snapengagement with said V-shaped groove extending entirely around theperiphery of and girdling said retainer pins.
